Several endocrine pathologies are commonly associated with ophthalmic involvement, such as diabetes and Gravesʼ disease. The parathyroid glands produce parathyroid hormone (PTH), which plays a key role in the regulation of calcium and phosphate levels in the blood. Dysfunction of these small endocrine glands can lead to various systemic manifestations. However, there is limited clinical information regarding a possible association between ocular manifestations and parathyroid gland disorders. We report here two cases of eye-related conditions associated with a history of primary hyperparathyroidism.
